This work is based on contextual vector quantization (cvq) compression algorithm with codebook optimization by simulated annealing (sa) for the compression of ct images. The lloyd and lbg algorithms are commonly used to optimize the codebook for a given dataset by iteratively clustering vectors and recomputing codeword averages. Label the two test vectors 0 and 1. when we got an input vector, compare it against the test vectors. depending on the outcome, the input is compared to the output points associated with the test vector closest to the input. after these two comparisons, we can discard half of the output points. Vector quantization (vq) is a technique that maps high dimensional vectors to codewords from a finite codebook. each codeword represents a region called a voronoi region. the lbg algorithm is commonly used to design vq codebooks by iteratively updating codewords to minimize distortion.
